You could try testing the post to see if it has ancestors, then, if so, retrieve the post titles of those ancestors and display them.

Example only.

<?php
// If you're using the_title();, I'm assuming you're in the loop
$pageID = get_the_ID();

if (get_post_ancestors($pageID) != '') {
 $post = get_post(get_post_ancestors($pageID));
 $title = ">> ".$post->post_title;
?>
} 

<span class='breadcrumbs'> > Home <?php echo $title; ?> >> <?php the_title(); ?></span>

This is off the top of my head, and would need to be improved (it only checks for the immediate parent, for a start, and mixing up the display of >> with the title of the parent is pretty klunky).

Might be easier just to grab a plugin to do it all for you:
